Thank you for your help.
Of course i know about the newObject() method and so on :)
What im really trying to do is to separate Caynne from POJOs so i could set
up "clear" DAO layer.
I wanted to have "saving" instructions in the DAO objects - i was going to
use "registerObject()" method - and this is where the problems with
relationships begin.
I just have to registrate object to Cayenne before doing anything.In my
(maybe dumb) opinion is not exackly how DAO layer should work (have to
"save" object before doing anything).
As far as i understand Hibernate was created to fit DAO model - and it works
perfectly.
Cayenne seems to have very different architecture in this matter. With the
need of registering the new objects in Cayenne (at the start) it's hard to
create perfectly "sterile" DAO layer.
It is possible but its much slower then using newObject() method and just
"mixing it all".
Cayenne wasn't created to work with "sterile" DAO layer, was it?:)
